Ramaroshan area is one of the prominent biodiversity-rich area outside the protected area network of Nepal and recently the researches on the aspect of biodiversity is gradually increasing (Acharaya et al. 2023; Tachamo-Shah et al. 2023), which is encouraging.  We need baseline information on the species’ distribution and abundance upon which tailored conservation measures can be initiated. However, this information should be based on the facts and evidence. Recently, Tachamo-Shah et al. 2023 have published an article entitled ‘Wetland biodiversity of Ramaroshan Lake complex: a need for conservation’ on JoTT 26 December 2023 issue. Much information in the article is promising, highlighting the additional attention the area should receive for conservation. However, there are some aspects, particularly those related to conservation status and endemism of amphibian species  which is misleading, making me to realize to write this response.

 

Endemism of species

The authors have mentioned two species of herpetofauna namely Small Paa Frog Nanorana minica and Marbled Cascade Frog Amolops marmoratus as endemic species (Tachamo-Shah et al. 2023). According to the IUCN Red List Assessment of the Small Paa Frog, the species is found in Uttar Pardesh and Arunanchal Pradesh of India and Bhutan (IUCN SSC Amphibian Specialist Group, 2022) which means they are not endemic to Nepal. Furthermore, the presence of Amolops marmoratus is mentioned with certainity for Myanmar only while for other regions the presence has been uncertain (IUCN SSC Amphibian Specialist Group, 2023a). Without photographic and other evidence, it is difficult to ascertain that the species has been identified properly.

 

Conservation status of the species

The authors have mentioned the worng conservation status for amphibian species. For instances, they have mentioned the Small Paa Frog as globally vulnerable species and the Indian Bull Frog Hoplobatrachus tigerinus as near thretened species (Tachamo-Shah et al. 2023). The Small Paa Frog is currently listed as the least concerned species (IUCN SSC Amphibian Specialist Group 2022). The species was listed as vulnerable species in previous assessment conducted in 2004. This could be due to the status being updated recently, possibly after the paper was submitted to the journal.

In the case of the Indian Bull Frog, the species was listed as least concerned species in previous assessment and it holds the same status in the recent assessment as well (IUCN SSC Amphibian Specialist Group 2023b).

 

Other issues

The name of the Liebig’s Paa Frog is Nanorana liebigii  which has been mentioned as Nanorana leibgii in the manuscript. Furthermore, despite Ramaroshan’s potential as site for Red Panda distribution, there is not enough evidence to support the presence of the species. However, they have failed to provide the details information about the means of confirmation.

 

Conclusion

Despite the attempts of the authors to bring the information on the status of important yet neglected wetland of Western Nepal, some information on the journal article needs reassessment and verification.
